Vacuum electrospray deposition for face-on orientation and interface preservation in organic photovoltaics.
Sci Rep
January 2025
Department of Physics, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, Republic of Korea.
Despite recent advancements in organic photovoltaics (OPVs), further improvements in power conversion efficiency (PCE) and device lifetime are necessary for commercial viability. Strategies such as optimizing the molecular orientation and minimizing the charge traps of organic films are particularly effective in enhancing photovoltaic performance. In this study, we successfully utilized vacuum electrospray deposition (VESD) to achieve favourable face-on stacking geometries while preserving the integrity of the interfaces in poly(3-hexylthiophene-2,5-diyl) (P3HT): [6,6]-phenyl-C-butyric acid methyl ester (PCBM) bulk heterojunction (BHJ) films.

Background: Blood clot formation, triggered by vascular injury, is crucial for haemostasis and thrombosis. Blood clots are composed mainly of fibrin fibres, platelets and red blood cells (RBCs). Recent studies show that clot surface also develops a fibrin film, which provides protection against wound infection and retains components such as RBCs within the clot.

Fruit spoilage caused by microorganisms results in huge economic losses and health risks worldwide every year. To develop an intelligent antimicrobial material capable of responding to the physiological activity of postharvest fruits and releasing antibacterial agents on demand, we fabricated a pH-responsive film for the release of chlorine dioxide (ClO) using carboxymethyl cellulose (CMC) and sodium chlorite (NaClO) via the solution casting method, with a CMC:NaClO ratio of 1:2 w/w. An acid environment simulated by 4 % acetic acid activated 43 % of ClO released by the film within 7 days.

To mitigate the risk associated with water-soluble fluoride in tea and to have less influence on the contents of tea infusion, a highly selective lanthanum modified silk fibroin (SF) and polyvinyl alcohol (PVA) composite film (SF/PVA-La) was prepared to remove fluoride from brick tea infusion. Notably, SF/PVA-La could remove about 48 % of the fluoride from in brick tea infusion within 30 min. Importantly, the reduction in total tea polyphenols in brick tea did not exceed 10 %, and the reduction in caffeine was only 0.

This study aimed to investigate the structural characteristics of Stichopus horrens collagen (SHC), Holothuria scabra collagen (HSC), and Holothuria leucospilota collagen (HLC) and to assess the effect of transglutaminase (TGase) on their film-forming properties. The results indicated that the collagens from three species of sea cucumbers were type I collagen with a complete triple helical structure. The thermal denaturation temperature of HLC (34.
